MACHINE FOR DRESSING MOLDINGS SPECIFICATION forming-part of Letters Patent No. 224,867, dated February 24, 1880.

Application filed January 6, 1880. ii

To all whom it may concern:

Be it known that 1, JOHN Gm BRANDON, of Detroit, in the county of Wayne and State of Michigan, have invented a new and valuable Improvement in Machines'for Dressing Moldings;.and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a longitudinal vertical section of myimproved machine for dressing moldings. Fig. 2 is a cross-sectional view of the bed and planer-stock. Fig. 3 is a plan view of the same, and Fig. 4 is a modification.

This invention has relation to certain im and it consists in the construction-and novel arrangement of the slotted bed, the adjustable bar under the molding, the adjustable rabbet-planer, and the bearings for holding the work, all as hereinafter shown and described. In the accompanying drawings, the letter A designates the bed, which is slotted transversely', as shown at b b, and is provided with a large opening, B, between these slots. Under-the bed, at the ends of this opening, are strong cleats or cheek-bearings G, which are also transversely slotted, as indicatedat d.

E represents the rabbet-planer, whichis designed to be of suitable length to fit neatly lengthwise between the ends of the opening B, the stock being not so wide as this opening, however, so that there is roomfor lateral adjustment. The ends of this stock are provided with arms or bearings D, which are vertically slotted at e, and extend downward,

being each in contact with a cheek-bearingf G, at the end of the opening. In this position the slot 0 of the planer-stock extends at right angles across the slot (1 of the cheekbearing, and a clamp-screw, g, passing through said slots, serves to fix the adjustment of the planer-stock, which may be varied laterally or vertically to suit the requirements of the work.

The construction of the plane-irons and bearing-plates may be similar to that set forth in the specification of my former Letters Patent, herein referred to, and one or several bits may be employed in the plane-stock, according to the character of the dress required.

F represents the'side bearing-frame, having the rollers or bearings h, and being provided with clamp-screws 70, which pass through the slots 72 of the bed and serve for securing the adjustment of the bearing-frame. Arms G, attached to the bed, extend over the same, and are connected to slotted bearings l, which are adjustable, and secured, by clamp-screws or other ordinary fastenings, to said arms, which are designed to have a slight spring action, so that the bearings Z, which have, preferably, rollers,will press on the work and hold it down after a shaving has been removed. These bearings are, therefore, located over and a little in rear of the points of the bits.

Under these bearings the molding passes, resting upon the' horizontal and longitudinal guide-bar H, which, when a rabbeted molding is to be dressed, is adjusted toward the side bearingframe, F, the adjustment being effected by means of the transverse slots 1) in the bed and clamps a, passing throughthe same to said guide-bar, as indicated in the drawings. er, which works in the rabbet, dressing its flange as neatly as desired.

The vertical and lateral adjustments of the rabbet-planer maybe varied to suitmoldings of different shapes and sizes, as hereinbefore indicated.

For side planing the planer-stock K is employed, this stock being connected to the bed by clamping-boltsp, passing through the transverse slots b, and in that manner rendered adjustable.

When the side planer is to be used, the rabbet-planer E is lowered and a piece of board is dropped in the opening at its side in the bed, so as to run the shavings over the side of the machine.

The molding passes over the plan- 7 Having described this invention, What I I In testimony that I claim the above I have 10 claim, and desire to secure by Letters Patent, hereunto subscribed my name in the presence is of two witnesses.
